Application filed July 12, 1881. (No model.)

To all whom it may concern Be it known that I, J OHN LANE, of Hyde Park,in the county of Cook and State of Illinois, have invented a new anduseful Improvement in Listing-Flows, which improvement is fully setforth in the following specification and accompanying drawings.

My invention relates toimprovementsin the construction. oflisting-plows, and the ob- I ject of myinvention is to simplifyandcheapen the construction, and to produce a more solid and light-weightfoundation than heretofore on which to build the plow.

My invention consists in a bent plate of flanges with perforations, incombination with a center bar and bent pl0w-beam, and with alisting-plowsharc having wings extending obliquely both right and left,and with two moldhoards, and bolts uniting the share and bothmold-boards to the flanges, all as hereinafter shown.

Figure 1 is a vertical sectional view ofa listing-plow, showing myimprovements. Fig. 2 is a top sectional view of same. Fig. 3 is a sideelevation of the bent plate A and center bar, B, showing the flange a.Fig. 4 is a top view of the bent plate A and the bent bar B, showing howthe flanges aand b are arranged. Fig. 5 is a cross-section taken on thedotted line a: w in Figs. 4 and 3.

A is the bent plate, consisting of a plate of iron or steel of theproperthickness and shape to form the two flanges a and b, and which Iunite to the forward end of the center bar, B, preferably by welding, asshown in the drawings. The flanges a and b are bent drooping and formedto fit the under side of the moldboards and share,and each flange hastwo per for-ations, c and h in the flange a, and cl and g in the flangeb, by which the wings y and z of the share S and the mold-boards m and'n are united to the flanges withbolts, as shown in Fig. 1. There is aperforation, 7c, in the forward end of the plate A, which I sometimesuse when making extra-strong plows.

S is the well known listing-plowshare, having the wings y and 2extending obliquelyboth right and left from the point, and the wing y isunited to the flange a with a bolt at h, and the wing z is united to theflange b with abolt at g, and the mold-board m is united to the flange awith a bolt at '0, and the mold-board n is united to the flange b with abolt at d, as shown in Fig. 2, by which the share, with its wings, andboth mold-boards are held rigidly together on the bent plate A; and A isan ordinary bent plow-beam, having its foot end united to the centerbar, and having side brackets,r 1', supporting the top of themold-boards, as shown in Figs. 2 and 1; and drill-teeth orsubsoil-blades may be attached, as shown in Figs. 1 and 2. t

The bent plate A may be united to the center bar with bolts or rivetsinstead of welded thereto, and the bolt at k may or may not be used, asdesired.

Havingthus setforth1nyinvention,Iclaim In alisting-plow, the combinationofthe bent plate A, forming flanges a and I), perforated, as shown, withthe center bar, B, bent plowbeam A, share S, having wings 3 and z, andthe mold-boards m and n, substantially as and for the purpose set forth.
